There are currently no unlocked and unbranded versions available for the GSM Blackberry Storm; however unlocking the phone will allow it to be used with any GSM service provider.
Firmware updates were released after December 2008 that addressed most of the critic's issues; updates can be downloaded online or over-the-air, and can be installed by the user.
If Black Berry Storm is used in Europe, Africa, Asia, Oceania or Brazil, HSDPA wireless data speed can be achieved, provided that the local GSM network supports it.
The phone will use the primary network technology of its intended carrier (Verizon) when traveling domestically in the US, and rely upon the GSM/UMTS/HSDPA networks of Vodafone mainly when traveling abroad.
It's not all fixes, though, as RIM has included additional functionality with the release as well.
